Lazy objects

The lazy.lazy object is a special helper object to specify a command for later execution. This object acts like the root of the object graph, which means that we can specify a key binding command with the same syntax used to call the command through a script or through qshell.


from libqtile.config import Key
from libqtile.command import lazy

keys = [
        ["mod1"], "k",
        ["mod1"], "j",
